Hashtable忽略大小寫

在.net1.1中這樣寫

Hashtable htTemp  =   new  Hashtable(  new  CaseInsensitiveHashCodeProvider(),  new  CaseInsensitiveComparer() );

到了，.net2.0後提示過期

是以可以像下面這樣寫。

class  myCultureComparer : IEqualityComparer

    {

         #region  IEqualityComparer 成員

         public  CaseInsensitiveComparer myComparer;

         public  myCultureComparer()

        {

            myComparer  =  CaseInsensitiveComparer.DefaultInvariant;

        }

         public  myCultureComparer(CultureInfo myCulture)

        {

            myComparer  =   new  CaseInsensitiveComparer(myCulture); 

        }

         public   new   bool  Equals( object  x,  object  y)

        {

             if  (myComparer.Compare(x, y)  ==   0 )

            {

                 return   true ;

            }

             else

            {

                 return   false ;

            }

        }

         public   int  GetHashCode( object  obj)

        {

             return  obj.ToString().ToLower().GetHashCode();

        }

         #endregion

    }

使用的時候

Hashtable htTemp1  =   new  Hashtable( new  myCultureComparer());
